Dust spots and bug
Good to hear you've located the bug and removed it, yep it might take a few attempts to ensure there's no fibers on the focus screen, but you'll get there.

Dust spots and bug
I once bought a M 40mm/2.8 that had a dead spider inside. :shock: To us it's precious gear, to the rest of the animal kingdom they're shelters! I've had corn lice, the pesky little black things in summer that stick to your arms, I've had them walk across the focus screen before.

Pentax K-5 time/date memory
As far as I know it's battery in but no need for the camera to be switched on. That assumes the internal battery is OK. I had a Fuji X-T3 one fail recently, it had to go back for a new mother board as the "battery" was built in.

Pentax K-5 time/date memory
but one thing that would have been nice is the ability to swap the battery from the base of the camera, rather than having to dismantle it to get to them, especially with (digital) cameras that are over 10+ years old still being more than usable. According to the guy in the shop, when I took the Fuj...

16-85mm lens gone wrong
Hi all, my 16-85 zoom lens has thrown up an issue. The autofocus works when focusing on a nearer object, but doesn't move when it needs to focus on a farther object. Had anyone else seen this?

16-85mm lens gone wrong
I had the 16-85mm for a while, didn't face the issue, however... Tipping you've tried cleaning the contacts on both lens and camera? Does it manually focus to infinity? (far objects)

16-85mm lens gone wrong
Thanks Rick. I'll try cleaning the contacts when I get back home, but my 55-300 is focussing fine so I think the body is ok, a K3

16-85mm lens gone wrong
That's positive news regarding the K-3 & 55-300mm, so unlikely to be the contacts, however worth a quick try of cleaning them. Reading around other sites, it seems that the 16-85mm can have various focusing issues, from jumping around after hitting focus or failing completely due to lose screws, ...

16-85mm lens gone wrong
Thanks, I'll check those things, it does focus manually. I'll clean it when I'm home next week, then debate whether to take a screwdriver to it or just call it a manual focus lens

16-85mm lens gone wrong
Sounds like an issue with the lens contacts or the 4 pronged contact thingy that tracks focal length and focus ring position. I'm guess the springy prongs might be bent. They might be accessible from underneath the rubber grip.

16-85mm lens gone wrong
I've also started having issues with the focus on my 16-85mm. It's fine at the widest end of the zoom but cannot quite get itself to the final focus if using the zoom, it requires a tiny bit of manual focus. My first copy never had any issue until I broke it. It's a very frustrating issue on a lens ...

16-85mm lens gone wrong
My copy started playing up a few days ago! It cannot focus at all when zoomed in, but can focus at the wide end. It was focussing as normal at the wide end, but I think that it now takes a few attempts to acquire focus. Such as shame as the image quality is stunning.

Just back from Dublin and can offer for those interested: * Patona Dual PD Performance Charger - fast charging via USB C (incl, as is the transport bag). This is a generic charger with two slots, and I have also got two plates for the Pentax D-LI90 batteries. These could obviously be replaced b...

FA20 lens profile
Hi Steve, I'm not a LR user, but I remain sceptical that Adobe develops it's own lens correction. I think your underlying problem is that the FOSS program lensfun doesn't support it as far as I can see. Link: You can submit images from the lens and hope that they pick them up and fee...

How to disable the back LCD-screen on my Pentax KP?
This is two fold, firstly turning off the screen, then secondly ensuring that it doesn't come back on when you turn the camera on/off. To turn off display: Click info button twice, scroll to the right 'off' option To ensure that it doesn't come back on, it needs to be remembered in the memory ...
